CONCENTBATING TABLE.

i Application filed September 11", 1924. Serial No. 737,085.

The invention relates to concentrating tables in general? and is directed primarily to a combined feed distributing and preliminary concentrating.apparatus designed,

.5 to operate in conjunction with concentrating tables-" 1 1 I Theobject of theinvention is to provide a concentrating table, with novel. means .by which materials mavbe fed in partially con- 10 centrated forin onto the table thereby facilitatingand expediting. the separation of the heavier from the lighter material and increasing the capacity of the table and securing a highly, efficient concentrating apl paratus especially adapted for the cleaning of c0al.'---

w I ,1 The invention consists of an auxiliary deck mounted on a transversely inclined differentially reciprocated table, the auxiliary 20' deckbeing-transversely'inclined in a direction opposite to the inclination of the table and adapted to receive the materials and de-' liver them in "partially concentrated form on'tlie table adjacent. the upper or feed side of the latter. i l I An embodiment of. the inventiontis illustrated in the accompanying drawings inwhichFigure 1.is aplan- View of a concentrating table having the invention applied thereto; Fig. 2 a cross sectionalview on line 1- -1 of Fig. 1; Fig. 3 a cross-sec tional view on line 3+3 of Fig. 1; Fig. 4 across-sectional view on line of-Fig. 1; Fig.v 5 an end view'of the mechanism 85 taken at" the head end' of the same; Fig. 6 a fractional cross-sectional View on line 6- -6 of Fig. 1 and. Fig. 7 a cross-sectionalview online 7'7 of-Fig. 5. l I? In the, illustrative embodiment of the in-- 4 vention 1 represents the main'deck of a con centrating table having the riflles 2 on its upper surfaceextending from the head end 3 of the deck toward the concentrates discharge end 4. The deck is'inclined downwardly from the feed side 5 toward the tailings dischargesi'deti. Suitable mechanism Tat the head end3of the deck and suitably connected to it is adapted to differentially reciprocate the deck in a direction substan l tially parallel'to'the rifiles 2.

The deck is: supported for longitudinal reciprocation upon the'bearings 8 of suitableformr An auxiliary deck 9, preferably somewhat triangular in shape, is disposed above the deck 1 and adjacent to the upper side and to the head end thereof. As shown in Fig. 5, the auxiliary deck is suitably pivoted at 10 to the head board 11 of the deck 1. The pivot (Fig. 7) comprises a casting 12 secured to the main deck by the bolts 12 The upper end of the casting is bifurcated to form a socket 13 for supporting an ap ertured boss 14 that projects from a casting 15 bolted to the auxiliary deck. A bolt 16 .is projected throughthe apertured boss, the

casting 15 and the frame of'the auxiliary deck and a nut 17' on the "outer end of the bolt 16 when tightened against a Washer 17 forces the 'washer against the opposed face of-the casting 12 and thereby locks the auxiliary deck to the main deck.- A bar 18 is secured to the head board '11 by the bolts 19, the bolts being laterally adjustable in slots 20in the board when the nuts 21 are loosened. The upper end of the bar '18 is slotted to recei-vea bolt 22 projecting from the head end of the deck'9 and it is also transversely corrugated as shown at 18-. A washer 23 on thebolt 22 secures the bar to the deck9 when the nut 24 is tightened, the .rear face of the washer being provided with teeth foreng'aging the corrugations on the bar 18. Thewasher tends to support the upper side of the deck 9' when the nut 24 is loosened so that adjustment of that deck is readily accomplished. The inclination of thedeck 9' is thereverse of that of the main deck -1 and when it is properly adjusted the bar 18 maintains the relative positions of theftwo decks. The opposite end or apex of the deck 9 is pivoted to the side board 25 of the main deck, the pivot being formed by an apertured socket plate 26 secured to the side board 25, in which socket is-the head 27 of a bolt 28 and Washer 29 the bolt being extended transversely through the aperture 30 in the plate 26, through a bearing 31 and through the adjacent end of the deck 9'and held tight by a nut 32 on the.

opposite end of the bolt. The socketforming portion of the plate 26 is convex and the opposing face of the bearing that contacts with the convex portion of the plate 26 is concave. By loosening the nut 32 and rection of reciprocation roifjthie decks. il -the I material to be treated is fed to the auxiliary deck i 9 -in;iihe spncefilaadjacent to the upper end :orf it-heidingonallside of ztheldeck :9.
